Ph.D. Position (w/m/d)

MARUM – Zentrum für Marine Umweltwissenschaften

Entgelt- / Besoldungsgruppe E 13 - Teilzeit 66%
Kennziffer: A6/21
Bewerbungsfrist: 17.03.2021
Öffentliche Ausschreibung

The MARUM - Center for Marine Environmental Sciences at the University of Bremen is offering (under the condition of job release) at the earliest possible date:

One Ph.D. position (f/m/d) for 3 years
Salary group 13 TV-L (66,6 %)

The employment is fixed-term and governed by the Act of Academic Fixed-Term Contract, §2 (1) Wissenschaftszeitvertragsgesetz – WissZeitVG. Therefore, candidates may only be considered for appointment if they still have the respective qualification periods available in accordance with § 2 (1) WissZeitVG.



At MARUM Ph.D. students are supervised by a team of experienced scientists. Additional training and support are offered by the Bremen International Graduate School for Marine Sciences, GLOMAR. These offers include expert as well as skills and methods courses, coaching, networking opportunities, and the opportunity to apply for internal funds. At MARUM, Ph.D. students acquire expert knowledge in their field and a solid background across many disciplines of marine sciences.
The work for the position lies in the general area of paleoclimate sedimentology and geochemistry. One overarching goal of this Ph.D. project will be the development of high-resolution Late Devonian XRF-derived elemental and d13C isotopic time-series to evaluate the possible role of astronomical insolation forcing in generating a depositional environment favorable for the burial and preservation of organic-rich sediments.

Specific duties will include:

  1. Field work and sampling of sedimentary rock in outcrops and quarries in the Rhenish Massif (Germany).
  2. Cutting and crushing of rock samples and carrying out X-Ray Fluorescence (XRF) analyses to obtain elemental geochemistry proxy series
  3. Constructing robust age-depth models according to the guidelines of the Cyclostratigraphic Intercomparison Project, and within an “Integrated Stratigraphy” framework
  4. Interpreting paleoceanographic proxy series in paleoclimate terms
  5. Presentation of research results at international conferences
  6. Publication of research results in peer-reviewed international scientific journals
  7. Opportunity for scientific qualification in the context of a PhD degree



  • A completed MSc degree, preferably in the Geosciences and/or Chemistry
  • Experience in paleoclimate sedimentology and an interest in geochemical laboratory methods
  • Experience in the interpretation of stable isotope geochemistry and/or elemental geochemistry results
  • Experience in stratigraphic techniques, time-series analysis and the construction of age-depth models
  • Applicants should have excellent English language skills and enjoy working in an international and interdisciplinary team
